Application filed March 18, 1921. Serial no. 453,271.

To all whom it may concern: Y I I Be it known that I, GEORGE H. VAN Box, a citizen of the United States, residing at Tampa, in the county of Hillsborough and State of Florida, have invented certain new and useful Improvements in Ventilating Toilets,of which the following is a specification.

This invention relates to.toilets, and the primary object of the invention is to provide a novel toilet embodying means for conveying obnoxious odors therefrom so that the same can not intermingle with the surrounding atmosphere. T

Another object of the invention is to provide a novel toilet bowl having a suction chamber therein, and passageways extending above the water trap in the bowl to said sue-- tion chamber, said passageways also tending to draw all of the noxious odors from the bowl abovethe water trap, said passage of paper in the'bowl.

A further object of the invention is to providein a ventilated toilet bowl a novel arrangement of passageways therein for conveying obnoxious odors therefrom, said passageways being so arranged as to prevent ways also tendiaig to facilitatet-he' placing the same from becoming clogged bypaper or other debris in said bowl.

A still further object of the invention is to provide a novel means for creatinga suction in said suction chamber, and anovel means for conveying the gases and odors drawn from said suction chamber to anoutlet pipe.

A still further object of the invention is to provide a novel means for preventing the back flow of the gases through said means for creatin a suction in said suction chamber of the oilet bowl.

With these and other objects in view, the invention consists in the novelconstruction,

arrangement and formation of parts, as will be hereinafter -more specifically described,

claimed and illustrated in the accompanying drawings, forming a part of this speci-I fication, in which drawings:

F s through a toilet bowl constructed 1n accordancewith this invention.

Fi the bowl taken on the line 2 2 of Figure 1, and

re 1 .is a vertical longitudinal section.

' equi-distantly spaced points with substan: :tially V-shaped slots '17, the purpose of re 2.is a horizontal section; through Figure 3 is a .detail enlarged vertical section through a portion of the suction creatlng means showing the'valve arrangement therein for reventing the back'flow of gases therethrougli.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates a toilet bowl; B a flush tank therefor, and Othe.

suction creatin means.

v The bowl A isconstructed along the general lines of the improved toilet bowl construction and is preferably formed of vitreous material as in the usual construction. As shown the bowl A includes the usual internal chamber 5' having the lower water trap 6, which communicateswith the usual waste pipe outlet passageway 7. The upper end of the bowl A is provided with the usual rim 8 which is provided with the internal annular flush water chamber 9, and this chamber communicates with the internal chamber 5,b-y means of a plurality of apertures 10. This internal annular chamber 9 has the usual communication with the flush water pipe 11- which extends downwardly from-the flush pipe B. This is the usual construction and does not form any part of my invention.

Directly below the internal annular chamber 9 is formed a second annular chamber 13, which will be hereinafter called the suction chamber, as in this chamber a draft is created, so as to form means for drawing all. obnoxious odors from the toilet bowl. Thislchamber 13 is provided with a laterally extending outlet passageway '14. which has connection with the suction creating means C as will be hereinafter more specifically described. Directly above thewatertrap 6 the internal chamber v5 is provided with a depending substantially annular flange 15, which is arranged in spaced relation to the wall of the water trap, and the lower edge of'this flange extends into or below-the level of the water in said trap which forms the seal.

:This' flange 15 forms an internal closed chamber 16 and this'flange is provided at which will be hereinafter vmore fully described. A plurality .of downwardly extendin passageways 18 are formed in. the bowl 3 and communicate at; their upper Specification of Letters Patent. 7 Patented Aug. g, 1922.

are provided with a plurality of branches 19 which communicate with the lower chamber 16. It can be seen from this construction, that when a suction is created in the upper chamber 13, all of the obnoxious odors in the bowl directly from and around the water tra will be drawn into the upper chamber 13 iiom said bowl, and thusthe flange 15 and the V-shaped slots 17 will prevent the passage of paper or other dbris in the bowl into the passageways 19 and thereby prevent the clogging up of said passa 'eways.

he suction creating means C for the suction chamber 13' consists of a suction fan 20. the inlet port of which is connected to a pipe 21, which is in turn connected with a trap pipe 22 and this trap pipe 22 is con-' nected by an elbow joint 22' with the laterally extending passageway of the suction chamber 13. The suction fan mechanism 20 can be driven in any preferred manner and as shown an electric motor 23 has been provided for driving this fan. The motor 23 has been shown arranged on a shelf bracket 24, which can be securely attached to a wall 25 arranged in rear of the toilet. The switch 26 for controlling the flow of current through the feed wires 27 of the motor can be secured in any preferred manner to the flush tank B on any convenient point which can be easily reached by the users of the toilet. The outlet port of the suction fan mechanism 20 has connected thereto an outlet pipe 28 which leads to a pipe 29, which can be embedded as shown in the wall 25. This pipe 29 can, if so desired. lead to the atmosphere to the outside of the building, or can be of the usual waste water type, if so desired.

It can be seen that in use of the improved device, it is merely necessary to turn the switch 26 when the toilet is in use and the suction fan mechanism 20 will be 0 erated, which will create a suction inthe c amber 13 and thus draw all of the obnoxious odors from the toilet bowl A and deliver the same to the pipe 29. This renders the toilet sanitary and removes all likelihood of disease.

being contracted from the escape of obnoxious odors or gases therefrom.

, The pipes 22 and 28 are provided with valve seat 30 on which are adapted to seat gravity actuated valves 31. The valves31 are provided with flanges 32 which are adapted to fit in the annular grooves 33 formed in the valve seats .30. This prevents the flow of fluid past the valves when the same are seated. The provision of. the valves precludes the possibility of gases flowing back into the bowl, when the motor is not in operation and it can be seen that whenthemotor is in o eration the valves will be automatically li ted off of their seats by the force of th'e'air flowing past the same.

If desirable one of the valvescan be' elimi- 1. A toilet bowl having an internal suc tionv chamber therein arranged above the water trap, a second chamber arranged adjacent to the Water trap and communicating with'the interior of the bowl and passage ways in said bowl connecting the chambers.

2. A toilet bowl having an internal suction chamber therein, and a water. seal, a chamber arranged directly above and adjacent to the water seal and communicating with the interior of the bowl, the bowl -having passageways connectin the suction chamber with the last mentioned chamber and means for" preventing the clogging o the passageways by debris in said bowl.

3. A= toilet bowl including a water'seal,

an internal suction chamber arranged in; the .bowl at .a point above the water seal, a .de-

pending flange formed on. the bowl and extending below the water line in said water seal, the flange forming an internal chamber and having V-shaped notches formed therein connecting the last mentioned chamber within the interior of the bowl, the bowl having passageways therein connecting the suction chamber with the last mentioned chamber and means ,for creating a suction in said suction chamber.

4. A toilet bowl having a water seal therein, a flush chamber, a plurality of open-' ings extending from the flush chamber com-- municating with the interior of the bowl, a

suction chamber arranged within the bo-wl below the flush chamber and having a laterally extending passageway communicating.

therewith, a. depending flange formed in said bowl and extending below the water line of said water seal forming a chamber,

the flange having a plurality of spaced V-shaped notches formed therein connecting the last mentioned chamber with the interior of the bowl, a plurality of passageways formed in the-bowl and communicating with the suctionchamber, the last mentioned passageways having a plurality of branch passageways connected with the last mentioned chamber, and means connected with said laterally extended passageway'of the suction chamber for creating a suction therein.
